This diverse discipline covers data from a wide variety of ground-based and aerial surveys and aerial photography. Baseline studies of habitat availability and habitat value assessments for bird and mammal habitat were based on aerial photography, and the results are presented and mapped for the study areas. The chapters also present the study results for presence, distribution and abundance, and/or habitat use for terrestrial mammals, raptors, waterbirds, shorebirds, landbirds, wood frogs, and seals in Iliamna Lake.
